FREIGHT-CAR.

Specification ot Letters Patent.

Application led January S, 1917. Serial No. 141,353.

lie it known that l. (ironie: S. (hmimu. a citi/.en of the i'nited States. residing at Philadelphia. inftl'ie county of Philadelphia and State of i)ennsylvania, have' invented a certain new and useful l `reightCar` of which the following is a specification.

The prinripal object of the present invention is to 'facilitate the rail transportation and unloading of grain and to this and other ends hereinafter setforth the invention. gencrall \v stated. consists in a hopper top freight ear from whieh grain can be easily dumped by inverting the ear` and which may bc provided with tight side doors well adapted to retain the mobile mass of grain and also useful in other connections and which. if desired. can be filled to the limit of its capacity.

From embodiments of the invention I ha ve selected one for illustration in thel accomlmnyingdrawings in which- Figure l. is a side view of a ear embodying features of the invention.

Fig. 2., is a top or plan view of the same.

Fig. 3. is a detail sectional view drawn to an enlarged scale, and

Fig. 4, is a detail view of one of the parts shown in Figs. l and 3.

A freight car embodying features of the invention is provided at the top with an inverted hopper, and a feature of the invention is the ease with which the grain can be dumped when the car is inverted. In the drawings, l, is an inverted hopper having its throat 2, at the top. By showing one inverted hopper I do notI intend to exclude the use of tivo or even more inverted hoppers. In the present instance the inverted hopper is also the roof of the car, thus providing fulleapaeity for the ear, but a roof can be put on top of the inverted hopper as will be readily understood by these skilled in the art; in any event due regard in outside dimensions must be had'to railroad specifications to avoid tunnels, bridges and other obstructions. 3, is a hatch which, when present, serves. to Close the throat of. the hopper and complete the roof of the car. 4, are side doors which', as shown, are adapted to close tight. They are of the hinge variety and are provided with bolt fastenings 5.

In use the car may be loaded with grain from above and through the mouth of the inverted hopper. if the Aear is to be used only in the grain trade and unloaded only at terminals provided with means for bodily inverting the cars. side doors may be dispensed with, but when the cars are used for Patenanee. 31, 191s.V

capacity, or substantially full, if they are` made sutticiently strong to avoid side-swipes. In the absence of side doors, or if the latter are of the tight-closing variety, waste of grain by leakage is avoided. If the grain is to be unloaded through the Side doors, false doors or planks 6, may be used to limit the outrush of grain. or this can be aeromplished by properly limiting the opening ot' the hinge door, or, if unobjectionable, it may be permitted to occur. In any event. the ear can be more conveniently and, if desi'aed, more fully loaded from the top than through the side. doors. One of the most important features of the invention is the facility with which the grain can be dumped when the car is inverted, and this is due to the inverted hopper at the top of the car, but. this same feature of construction and ar4 rangement makes possible other advantages of which some have been mentioned and of which others are obvious to those skilled in the art. To unload a grain car through its side doors presents difficulties which are well understood and requires a great deal of time and labor', and often entails Waste but. by my invention these difficulties are avoided and much time and labor are. saved and Waste avoided.

Modifications and changes maybe made inV details of vconstruction and arrangement without departing from the spirit of the invention, hence I do not limit myself to such matters but what I claim is: y

1. A freight car having a generally recles ' haagse tangular interior box-like. in its adapt-ability tangular interim` box-like in its adaptability for 'freight and having at its top an n- 'for freight and having side doors and proveltted hopper` through which grain can be vided at its top with an inverted hopper dumped by inversion of 'the carr to l easily having at its throat a hatch, substantially as 10 5 unload it, substantially as described. described.
